Embodiment Construction

[0055]The present invention is directed to hollow iron-type golf clubs and can also be used with utility golf clubs. The inventive iron-type golf club provides the aesthetics of a muscle back iron while moving the center of gravity lower and further back, increasing moment of inertia, and enlarging sweet spot similar to a cavity back club. The inventive club can accomplish this goal by incorporating a hollow interior cavity in the muscle portion of the club, supporting a thin hitting face with a supporting member, and adding a high density rear sole portion. Additionally, weight from the upper toe can be redistributed to other portions of the club head to improve mass characteristics, and can be advantageously replaced by a vibration and sound dampener. The end result of the present invention is a club that resembles a muscle back iron that low handicap players use, but the club plays like the forgiving cavity back irons that high handicap players prefer. Several embodiments of the ...
